  • Signs: dyspnea may be seen at a few weeks old if severe, eg if other obstructing conditions. Exercise intolerance.
  • Diagnosis: clinical signs and radiology.
  • Treatment: supportive, surgery for other components of brachycephalic airway obstruction syndrome but not without risk.
  • Seen in Bulldog Bulldog. May remain subclinical in adult until exacerbated by brachycephalic airway obstruction syndrome Brachycephalic airway obstruction syndrome.
